A young man with a political pedigree is one of few Republicans publicly criticizing U.S. Rep. Scott DesJarlais and says he won't rule out making a primary election run in the 4th District.

DesJarlais says his views have evolved since he supported abortions by his former wife and said he will not resign although he deeply regrets past relationships with multiple women, including patients and co-workers.

Weston Wamp, 25, lost a Republican primary in August to incumbent 3rd District U.S. Rep. Chuck Fleischmann.

The son of former U.S. Rep. Zach Wamp told the Chattanooga Times Free Press that any decision to challenge DesJarlais is "on the backburner," but indicated he is weighing the option.
